A hand signal to indicate that you want to take another card on your blackjack hand. When a dealer hits on soft 17, the house edge increases by about 0.22%. While this may seem negligible, it can make a difference for advantage players who are aware of this rule and adjust their strategy accordingly. In theory, this is how soft hands are defined. Now let’s have a look at some of the possible card combinations that you can get during the course of the game. For instance, if you get dealt an ace and a four, this is soft fifteen. Let’s assume that the dealer has a strong up card and you decide to improve your hand by hitting. You happen to draw an eight but instead of going bust, you can simply switch the value of the ace to one. This is one of the reasons why the ace is considered to be the most powerful card in the deck as it gives you a great flexibility and freedom to play with your hand’s total.
